Elgin Grade 711

Here is an Elgin grade 711 13/0 size, 17 jewel, wristwatch movement.

This Elgin design does not have banking pins. Instead, the pallet bridge extends down at the outer portions of the circular cutout visible here, and into the path of the pallet fork, blocking it side to side. Of course something like this is not adjustable, but that should not be necessary on a later watch like this.
